    Abstract: A frequency hopping processing method and apparatus are disclosed, where user equipment receives frequency hopping information, which is sent by a network device, of an extended transmission time interval (TTI); and determines a frequency hopping area of the extended TTI according to the frequency hopping information of the extended TTI. The frequency hopping area of the extended TTI and a frequency hopping area of a normal TTI do not overlap in frequency, and during M-PUSCH frequency hopping of each extended TTI, the user equipment can hop into a corresponding M-PUSCH frequency hopping area according to a preset frequency hopping pattern, and does not hop into a PUSCH frequency hopping area, so that a resource conflict does not exist when M-PUSCH frequency hopping of an extended TTI and PUSCH frequency hopping of a 1 ms TTI are performed at the same time.

    Abstract: This application provides a data communication method, a terminal, and a base station. In one embodiment, the terminal receives a first demodulation reference signal based on a first physical resource block index, wherein the first physical resource block index is determined based on a first location in frequency domain, and the first demodulation reference signal is usable for demodulating a first data channel for carrying a system information block; the terminal sends and/or receives a second demodulation reference signal based on a second physical resource block index, wherein the second physical resource block index is determined based on a second location in frequency domain, and the second demodulation reference signal is usable for demodulating a second data channel other than the first data channel.

    Abstract: The middle subcarrier of the baseband OFDM signal of each numerology may need to be shifted appropriately with respect to other numerologies to comply with a nested grid. These shifts can be signalled to the UE with an associated overhead. Methods and systems are provided to reduce overhead for OFDM communication. Reduced overhead can translate into increased bandwidth for the system, and/or reduced power/battery consumption in the UE. A transmitter generates an OFDM signal associated with a first subcarrier spacing of a first numerology (μ), a middle subcarrier frequency of a set of usable resource blocks (RBs) of the first numerology being offset from a carrier frequency by a first offset having a value (k0,xμ) in units of subcarriers, the value of the first offset being defined by a specific formula. The transmitter transmits the OFDM signal according to the first subcarrier spacing and the first offset.

    Abstract: Embodiments of the present disclosure provide a method for determining a control channel search space. The method includes: determining numbers of at least two physical resource sets; determining, according to the numbers, location offsets of search spaces corresponding to the at least two physical resource sets, wherein the determined location offsets of the search spaces comprises at least two different location offsets of the search spaces; and determining, according to the location offsets of the search spaces corresponding to the at least two physical sets, the search spaces corresponding to the at least two physical resource sets. By grouping and numbering resources, and determining different location offsets for different search spaces, a probability of control channel search space conflict can be reduced. Thereby, resources of control channels can be maximized in a case of multiple users, and communication efficiency can be improved.

    Abstract: The present invention provides a information processing method at a terminal or a base station. The method at the terminal includes: receiving scheduling information of a physical downlink shared channel (PDSCH) carrying system information, the scheduling information of the PDSCH carried in a master information block (MIB) or downlink control information on an enhanced physical downlink control channel (EPDCCH) sent from the base station, wherein the scheduling information of the PDSCH is used for determining at least one kind of transmission information of the PDSCH; determining the transmission information of the PDSCH according to the scheduling information of the PDSCH. In this way, an extra overhead of a control instruction when a PDCCH is used to schedule a SIB in the prior art is reduced.
